similar to: [LLVMdev] The annotation intrinsic, floating point values, stores and branches

Hi, Thank You for the advice and we were able to solve that problem by the following modifications to the Instrinsics.td file. But I now have an "Invalid Intrinsic name" error This error occurs presumably because the created intrinsic is named: llvm.migrate_begin.i32 Intrinsics.gen checks for a string length of 18 (i.e. the length without the .i32). Kindly help me through it.

Hello again, I really need to know how to make llvm understand the annotate in C++ code or to write a new Intrinsic by myself. I tried to add a new Intrinsic corresponding to the ExtendingLLVM doc instructions, but it is too opaque and I faild. Please, advise me if you can. Sincerely, Hripsime.

Hi all, I need to use annotate inside the C++ code and want to know why doesn't it work? How can I modify my sources to use annotate inside the C++ code too? Thanks in advance.

I'm trying to insert some annotations using the @llvm.annotation.i32 intrinsic. When I compile the file with llc, it gives me the error "LLVM ERROR: Cannot select: intrinsic %llvm.annotation". My IR file looks like this: $ cat test.ll @.str = private unnamed_addr constant [6 x i8] c"Hello\00" declare i32 @llvm.annotation.i32(i32, i8* , i8*, i32) define i32 @main(i32

To avoid going too off-topic on the multidimensional gep thread, I'm asking this in a separate thread. >> I took a look earlier and didn't notice any target-independent ones that would need a separate type parameter Do you know what would happen with the llvm.ptr.annotation intrinsic? Frontends use that to annotate members of structs: struct S { [[some_annotation]] int

There are a few instrinsic functions I would like to remove, is this possible? For example, the llvm.lifetime and llvm.dbg instrinsics? You can't simply iterate over the funciton and remove the call instructions, this causes issues. Is there a known structured way of doing this? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi,all. I've been reading the llvm source code for some days. Here is my problem: what does instrinsic / intrinsic function really means? Are these "the function belong to llvm and just belong to llvm"? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, LLVM is used to have an llvm.x86.and_ps instrinsic for the ANDPS instruction, but it seems to be gone, and it is a bit hard to synthetize it from vector instructions, since 'and' only works on vectors of integer types. Would a patch be accepted which adds this and related instructions back ? Zoltan -------------- next part -------------- An HTML attachment was

Having multiple different uses cases during the bring-up would be very helpful to

Hello all, According to *clang/lib/CodeGen/CodeGenFunction.cpp*, a LLVM annotation intrinsic call has 4 arguments: - llvm::Value *AnnotatedVal, - Builder.CreateBitCast(CGM.EmitAnnotationString(AnnotationStr), Int8PtrTy), - Builder.CreateBitCast(CGM.EmitAnnotationUnit(Location), Int8PtrTy), - CGM.EmitAnnotationLineNo(Location) However, this is what an annotation intrinsic *char

Hello, I have a problem with pattern matching on intrinsics. I have following code in IntrinsicsX86.td: ``` let TargetPrefix = "x86" in { // All intrinsics start with "llvm.x86.". def int_x86_mpx_bndmk: Intrinsic<[llvm_x86bnd_ty], [llvm_ptr_ty, llvm_i64_ty], []>; } ``` And following instruction that is generated when @llvm.x86.mpx.bndmk is used in code:
